Ash-sifting apparatus.



supported on the body in Such Inanller that the j0int between the tW0 is br0ken and the escape of dust rec111ded, and yet the thr0at I1l1y When I1ecessity arises be readily-1ifted 0 the body and aS readily replaced thereon The Side va1lS 2 0 the body 12 are I'0 vided on their upper edges With inwardly directed flanges 25 Figs. 3 and 4E, and the tO Wall 26 is inter10cked With Sid flngeS 25, as indicated by 27 t0 break j0ints betveen the parts, strongly connect the San1e, and lend rigidity and strength t0 the body as a Wh0le, as well as t0 permit of the Wa11 26 being dravn out Of engagement vvith the vva11s 2 vhen it is desired t0 Shi OI' Store the body in a knock-down Stte. Lt its 10Wel' end the wa11 26 iS inteT10cked With the u er end of the bie late 15 aS indicted by 28 Fig 1 and at its upper end Said Wall 26 is inter10cked With an upstanding vvall )0rti011, as indicated by 29. Ihtls vvhen it iS desired t0 remove the v11 26 from wans 2, it is Simply necessary as I Condition recedent t0 0pen the j0ints 28 and 29 vvhereup0n'the vvall 26 1Tlay be vvithraWn endwise from the 0Sition Shown in The botton1 Wa11 30 0f the b0cly 12 is Connected by intef10cked j0ints 31, Iig 2, With the side Wa11S 24=, and hence Sai(1 bottoln Tvall is Strong1y connected t0 the Side Tvalls in a dustr00f br0ken j0int 111)Ilner, and yet the b0ttom Wa11 my be 1'edi1y With` `d1'...t'vx,11 from engagement with the side vva11s for kn0ck-down purp0ses.

The a1"S Of my nove1 apptratt1s that are forIned 0 f*nleta1 0ther than galvanized Sheet il0I1, are tlle shafts, the gerS there011, the counterba1ance Veight, the brackets, and the connecting b01ts.

vv1en deeIned expedient the Screen 13 nay be mounted in the body 12 S0 as to be Slipped endwise int0 and out of Working 0Siti0!1, S When it is desired t0 use screens having interstices Of different Sizes 0I' t0 I'6 lace a WOTn-Out screen vvith a IleW One. This, I10vvever, is not Of the essence 0f ]Ily invention an(1 I l1[ve therefore regarded it as unnecessary to illustrate same I have entered int0 a detai1 desc1'ipti0n Of the constructi011 ndre1ative arrangement of the arts embraced i11 the resent and referred embodiInent 0 Iny inventi0n in ordef t0 iInPart2tfu11,01ear and exact underStnd ing Of the Said elnb0dinlent.
